Traders artificially inflate the price of small cryptocurrencies with the hope of making a quick profit at the expense of other investors.

Business Insider observed five apparent "pump and dumps" of coins in just a week, coordinated using the messaging app Telegram. See how they work here.

The activity would be illegal in most markets, but regulators have yet to get to grips with cryptocurrency sector, which has exploded in size to $200 billion in 2017.

Those who monitor the secondary market say "this sort of activity is rife" and "a real problem."

LONDON — Cryptocurrency exchanges are rife with "pump and dump" scams that would be illegal in most markets and leave unsuspecting investors at risk of large losses, a Business Insider investigation has found.

Crypto traders are using the secure messaging app Telegram to orchestrate the scams. Their strategy is to suddenly inflate the price of a cryptocurrency by coordinating a few buyers to act at specific times.

Then, after the price rises, they attract other, unwitting investors to buy into the price momentum. The "pumpers" quickly sell the coin to make a profit. The coins often crash just minutes after the initial surge, leaving the second wave of investors with losses.

Business Insider observed pump-and-dump schemes for the cryptocurrencies UBQ, VCash, Chill Coin, Magi Coin, and Indorse over the past two weeks alone. All the scams took place on either the Las Vegas-based exchange Bittrex or the Russian exchange Yobit.

Ben Yates, a senior associate at the law firm RPC who has looked closely at the space, told Business Insider: "It's clear from even casual monitoring of the exchanges that this sort of activity is rife, particularly with altcoins with smaller circulation."

Cryptocurrency exchanges and markets are unregulated in most parts of the world, and so these activities are not illegal. Still, they highlight the risks associated with this new corner of finance, which has attracted huge amounts of capital in 2017 but is regarded as the Wild West by critics.

Pump-and-dump schemes are illegal in government-regulated public stock markets, like the London and New York stock exchanges. Several securities lawyers Business Insider spoke with argued that cryptocurrency exchanges should be regulated in the same way. The US Securities and Exchange Commission has said digital currencies are likely to fall under existing securities laws, but it has so far taken little enforcement action.

A $200 billion market

Cryptocurrencies have exploded in popularity this year thanks to the success of so-called initial coin offerings, in which startups issue new digital coins in exchange for real money used to fund their ideas. These coins can be traded on online exchanges, offering greater liquidity to investors in private companies.

The boxer Floyd Mayweather Jr. has promoted an initial coin offering. Ethan Miller/Getty Images Over $3 billion has been raised through ICOs this year, and there are now more than 1,200 cryptocurrencies in circulation, according to CoinMarketCap.com. Celebrities such as Paris Hilton, the boxer Floyd Mayweather Jr., the rapper The Game, and DJ Khaled have all endorsed ICOs, helping raise the profile of digital currencies.

While retail investors have rushed into the new market, many people have warned about the potential dangers of the emerging space.

The European Securities and Markets Watchdog on Monday said ICOs were " extremely risky and highly speculative investments" and "many of the coins or tokens ... have no intrinsic value other than ... to use them to access or use a service/product." Investors risk "the total loss of your investment", ESMA warned.

Despite similar warnings from other regulators, the cryptocurrency market has ballooned to almost $200 billion this year. Well-known coins such as bitcoin, Ethereum, and bitcoin cash account for 80% of the market by value, meaning a huge number of low-value coins are circulating. Most have thin trading volumes, making them ripe for pump-and-dump manipulation.

'Market manipulation 101'

"Pump and dump" scams involve people artificially boosting the price of an asset before offloading it to unsuspecting investors at the higher price.

Scammers first organise coordinated buying of a particular coin on a set exchange at a set time. The wave of demand pushes up the price.

The "pumpers" then use social media, online discussion forums, and message boards to attract new buyers. They generally argue that the price spike is evidence of a sustained rally. The pumpers then offload their coins to the new buyers who come into the market at a higher price. In most cases, this coordinated "dump" depresses the price of the coins back to their pre-pump levels.

It's unclear how frequently those involved in the pump-and-dump schemes profit from them, as there is no way to guarantee that any given pump will attract enough new buyers into the market.

Mati Greenspan, a senior market analyst at the trading platform eToro who covers the cryptocurrency markets, told Business Insider: "Pump-and-dump schemes are a real problem. Besides the fact that it is illegal and unethical, the results can be incredibly unpredictable."

Regardless, such market manipulation would be illegal in most regulated markets whether or not the participants profited.

Ben Kingsley, a partner at the law firm Slaughter & May who specialises in financial regulation, told Business Insider: "If you're organising people to say, 'This is fantastic — I'm amazed everyone's not piling into it,' as a way to stimulate demand with a view to then selling into a rising market, that's market manipulation 101."

Yates of RPC said: "The sorts of coordinated pump-and-dump activities we are seeing on cryptocurrency markets would fall foul of numerous prohibitions were they carried out on stock markets — they are practically textbook examples of market manipulation and false trading, for example."

'PumpKing Community'

Those involved in the manipulation often make little effort to hide their activities. The pumping of coins is regularly referred to in Telegram groups where they are organised.

One group, PumpKing Community, contained links to "Instructions for pump on Bittrex" as well as links to Facebook groups and Telegram channels where pumpers could go to attract new investors to the market.

Channels like these attract participants to the scam with promises of wealth and quick profits. The PumpKing guide said: "Our PUMP will consist of 4 main stages, and we strongly recommend that you divide your deposit into 3 parts in order to get the maximum profit."

The admin of the PumpKing Community channel on Telegram goes by the name of Ton Montana, an apparent reference to the film "Scarface."

Telegram is heavily encrypted, and users can hide behind aliases, meaning it is difficult to track those involved. Ton Montana did not respond to a Telegram message sent by Business Insider.

It is unclear how many people are involved in pump-and-dump scams, but groups coordinating them have thousands of members. PumpKing Community has more than 14,000 members.

Brian Schuster wrote in a blog post: "Many users who bought at the peak (called bag holders) will often be left holding a cryptocurrency with declining value. These buyers are the true targets of these pump and dumps, the users who will pay 10x to the insiders for a cryptocurrency that is actually worthless. And once the price rises and falls, [it] will almost never return in value."

Business Insider/Oscar Williams-Grut/Screenshot/Telegram Kingsley of Slaughter & May said he thought regulators "ought to" take the same approach to policing these scams in the token-trading world as they do in relation to securities because "it creates the same harm."

"It causes unwitting investors to suffer a loss, and it undermines the integrity of those markets," he said.

"There is definitely some legitimate value-adding activity going on in the cryptocurrency and public coin offering space — not all of it is chancers and con artists. But the problem is when you have activity that either definitely is or might be of that nature, it undermines confidence."

It is unclear whether the exchanges Yobit and Bittrex are aware of that pump and dumps are occurring on their platforms. Yobit did not respond to a request for comment from Business Insider.

Asked for comment via its online form, Bittrex said: "Due to an unprecedented amount of growth in a relatively short amount of time we're experiencing a longer than usual wait time responding to and resolving your requests."

The message gave no specific comment on the points put to the company by Business Insider. Bittrex said in its message that the company was "actively training new personnel and streamlining our support system to better handle the demand."

Bittrex advertises on its website that it was "one of the first companies to apply for New York's Bitlicense," a bitcoin trading license conceived by the New York Department of Financial Services. The NYDFS declined to comment on whether it was aware of pump-and-dump scams in the cryptocurrency market or whether it was investigating activity on Bittrex.

Jackson of Mangrove Capital told Business Insider: "Regulators will slowly move towards a solution, recognising the value in ICO for the long-term balanced against the need for a proportionate regulatory framework with significant penalties for avoidance or transgression."

He believes the market will move to self-regulate, with exchanges making sure participants "act in certain ways and with good procedures" in the same way stock exchanges and the Lloyd's of London insurance market do.

The companies behind the coins Business Insider witnessed being pumped — UBQ, Chill Coin, Magi Coin, and Indorse — could not be reached for comment. VCash did not respond in time for publication.
